<div id="classDescription">
CExistValidator validates that the attribute value exists in a table.
<br/><br/>
This validator is often used to verify that a foreign key contains a value
that can be found in the foreign table.
<br/><br/>
When using the <a href="CExistValidator.html#message">message</a> property to define a custom error message, the message
may contain additional placeholders that will be replaced with the actual content. In addition
to the "{attribute}" placeholder, recognized by all validators (see <a href="CValidator.html">CValidator</a>),
CExistValidator allows for the following placeholders to be specified:
<ul>
<li>{value}: replaced with value of the attribute.</li>
